Исследование проведено на монокристаллах, деформация в которых осуществляется вдоль осей [<xref ref-type="bibr" rid="cit001">001</xref>], [ 39], [ 22] и [ 34]. Измерены энергии активации ползучести для исследованных ориентаций. Определено, что скорость установившейся ползучести описывается известным законом dε /dt = K2σn. Получены величины показателя степени n, делаются выводы о возможных механизмах ползучести. Показано, что ползучесть образцов, ориентированных вдоль разных осей, определяется дислокационными процессами, которые различаются энергией активации.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the research results of different characteristics of the Ni3Ge alloy possessing L12 structure. The research of single crystals is carried out. Their deformation is oriented along axes [<xref ref-type="bibr" rid="cit001">001</xref>], [ 39], [ 22] and [ 34]. The activation energies of creep for the investigated orientations are measured. The steady-state creep rate is described by the well-known law dε /dt = K2σn. Values of the steady-state stress exponent, n, are received. Conclusions about possible mechanisms of creep are done. It is shown, that creep of the samples oriented along different axes is carried out by the dislocation processes with different activation energies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ползучесть</kwd><kwd>интерметаллиды</kwd><kwd>энергия активации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>creep</kwd><kwd>intermetallic compounds</kwd><kwd>activation energy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ в  рамках научного проекта № 14-02-92605 КО_а.</funding-statement><funding-statement xml:lang="en">The reported study was partially supported by RFBR, research project no. 14-02-92605.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hemker K.J.
